Catholic Social Teaching

Catholic Social Teaching (CST) is the body of doctrine developed by the magisterium of the Catholic Church, beginning with Pope Leo XIII’s encyclical Rerum Novarum (1891) and elaborated through subsequent encyclicals, papal addresses, and the Second Vatican Council, that articulates the Church’s understanding of economic, political, and social order in light of Catholic moral theology and natural law. The teaching is not a political programme. It is an articulation of moral principles applicable to political and economic questions, leaving the prudential application of those principles to lay Catholics acting in their particular circumstances.

The four principles around which the body is conventionally organised are: the dignity of the human person, the common good, subsidiarity, and solidarity. These structure the teaching’s responses to particular questions of property, labour, the family, the state, war, and the international order.

Key Takeaways

• The body of papal and conciliar doctrine, developing from Rerum Novarum (1891) onward, on economic, political, and social order.
• Organised around four principles: human dignity, the common good, subsidiarity, and solidarity.
• Distinct from both socialism (rejected for its denial of private property and the family) and unrestrained capitalism (rejected for its reduction of persons to economic units).

History And Context

The discrete tradition begins in 1891. Leo XIII’s Rerum Novarum responded to the social crisis of late-nineteenth-century industrial capitalism — the appalling conditions of factory labour, the rise of socialist parties, the decline of the guilds and confraternities that had structured pre-industrial economic life. Leo defended both the right of private property (against socialism) and the rights of labour to just wages, decent conditions, and free association (against unrestricted capitalism). The encyclical established a method that has remained constant: the magisterium articulates principles drawn from natural law and revelation, then leaves political application to the practical judgement of lay Catholics.

Subsequent landmarks: Pius XI’s Quadragesimo Anno (1931), which defined subsidiarity and developed the critique of “social modernism”; John XXIII’s Mater et Magistra (1961) and Pacem in Terris (1963), extending the teaching to international questions; the Second Vatican Council’s Gaudium et Spes (1965), the Church’s longest treatment of the modern world; John Paul II’s Laborem Exercens (1981), Sollicitudo Rei Socialis (1987), and Centesimus Annus (1991), the most extensive papal contribution; Benedict XVI’s Caritas in Veritate (2009); Francis’s Laudato Si’ (2015) and Fratelli Tutti (2020).

The Pontifical Council for Justice and Peace’s Compendium of the Social Doctrine of the Church (2004) provides the authoritative synthesis.

The Conservative Position

CST occupies a particular place in conservative thought. American conservatives have engaged with it asymmetrically — drawing on its principles of subsidiarity, the family, and the moral content of economic life, while sometimes uneasy with its strictures on labour rights, on warfare, and on the unrestricted operation of markets. The traditionalist and Catholic-conservative wings (Patrick Deneen, Adrian Vermeule, First Things, the Witherspoon Institute, the American Affairs circle) have made CST much more central to their political thinking than the libertarian or fusionist wings.

Three principles do most of the work in conservative engagement.

The dignity of the human person. CST grounds political and economic order in the moral status of the person, made in the image of God, possessing inherent worth that prior any social or political determination. This is the fixed point against utilitarian calculations of policy and against ideologies — racial, class-based, or technocratic — that subordinate the person to a collective.

The common good. The political community exists to enable its members and their associations to attain the human goods proper to them. This is a substantive conception, not procedural; the common good is not the sum of individual preferences but the conditions of shared flourishing. The conservative use of this principle is the basis for the critique of liberal political theory’s procedural neutrality.

Subsidiarity. Decisions should be taken at the lowest level of authority capable of taking them well; higher authorities should support lower ones rather than absorb them. Pius XI’s Quadragesimo Anno gave the principle its classical statement and made it binding doctrine. Subsidiarity supports both the conservative defence of mediating institutions and the case for limits on the central state.

The fourth principle, solidarity, has been more contested in conservative reception. CST’s solidarity demands that the wealthier and more powerful support the conditions of flourishing of the weaker and less powerful — a substantive obligation, not optional charity. This produces tensions with libertarian accounts of property rights and with versions of conservatism that treat the state’s redistributive role as inherently illegitimate. Catholic conservatives have typically argued that solidarity calls for action through mediating institutions and through morally formed market exchange, not for state redistribution as the default instrument.

Differing Positions

Liberal political theorists have argued that CST’s substantive conception of the common good is incompatible with the procedural neutrality liberal democracies require — that to enforce CST’s view of the family, of property, or of the international order would be to impose a particular comprehensive doctrine. The Catholic reply, articulated most fully by John Courtney Murray and developed by John Finnis and Robert P. George, is that political authority cannot in fact be neutral about the human good and that the question is which substantive conception of the good will inform it.

Libertarian and free-market critics have argued that CST’s defence of labour rights, of just wages, and of state involvement in social welfare functions amounts to soft socialism. The reply, sustained by John Paul II’s Centesimus Annus and by the Acton Institute’s reading, is that the principles are compatible with a market economy that is morally formed and institutionally limited; the rejection of socialism is explicit in Rerum Novarum and has not been retracted.

Liberation-theology readings of CST, particularly in mid-twentieth-century Latin America, drew on the principle of solidarity to support more radical political programmes than the magisterium endorsed. The 1984 and 1986 Vatican Instructions on liberation theology drew the line.
